The American Cockroach. Questo articolo non è disponibile.The American Cockroach

This volume deals mainly with the biology of the American cockroach, Periplaneta americana (1.). Contributors were urged to emphasize recent findings, including unpublished data when possible, a goal that would not have been feasible if it were not for the two previously published books on the basic biology of cockroaches, The Biology o/the Cockroach (1968) by D. M. Guthrie and A. R. Tindall and The Cockroach, Volume 1 (1968) by P. B. Cornwell. Those topics not included in The American Cockroach, such as external morphology, are well covered in the two preceding books. In addition, these books provided a broad background upon which contributors to The American Cockroach have been able to build with recent trends, new and established concepts and integration. Although this book deals primarily with the American cockroach, many chapters offer a comparative approach in sections where the more recent and exciting research has been accomplished on other species. Most contributors place the cockroach in perspective with regard to its appropriateness or inappropriateness for various types of biological investigations. Many questions are realistically left unanswered when no acceptable or obvious solution is apparent; an invitation to new researchers to consider the cockroach as an experimental subject.
